Neuro-stimulation and Sensor Devices Comprising Low-Impedance Electrodes, and Methods, Systems And Uses Thereof

Disclosed are platforms to enable lower impedance electrode array, together with a miniaturized battery pack. Lower impedance can be achieved by different approaches, according to the invention, including surface modifications, preferably in nanoscale. Also disclosed are articles and control systems comprising medical implant neural stimulator devices, neural diagnosis tools, spinal cord and peripheral nerve stimulations, and cochlear implants. More particularly, the invention discloses means for reducing pains in human body, utilizing innovative components and systems comprising an epidural lead having multiple electrodes at a distal end, the electrodes being configured in an array and being selectable to provide either unilateral or bilateral neural stimulation. In an example, advanced spinal cord stimulation (SCS) electrodes having pre-designed novel, metallic or non-metallic nanostructured surface with desirable high-aspect-ratio nanopillar features for superior neural electrode functionality exhibiting significantly reduced electrical impedance are disclosed.
